Rib is a variant of the Plain weave. It is created very correspondingly to a plain weave. The basic construction follows the same pattern, modified by extending it warp or weft way or both.

Rib weave is a basic weave which produces ribs on the fabric. Resulting fabric is abrasion and tear resistant examples of which are broadcloth, cord fabric, faille, poplin, taffeta etc.

Properties :

The dissimilarity can also be that Rib weave uses one heavyweight yarn. This is used for either the warp of weft yarns and the end result is a fabric that has raised ribs either horizontally or vertically down the fabric, depending on whether the heavier, thicker yarn is used for the warp or the weft.
